Banglore

Explanation: The Southern Regional Load Dispatch Centre (SRLDC) is one of the five regional load dispatch centres in India, mandated under the Electricity Act, 2003. It is headquartered in Bengaluru, Karnataka, and serves as the apex body for ensuring integrated grid operation in the Southern Region.

Working Principle: The SRLDC functions as the nerve center of the regional grid, utilizing a SCADA (Supervisory Control and Data Acquisition) system and EMS (Energy Management System). It monitors grid parameters like frequency, voltage, and power flows in real-time to maintain the security and stability of the regional grid. It coordinates the dispatch of power from Central Generating Stations and manages interstate transmission lines to ensure optimal grid performance.

Key Formulas: $P = \sqrt{3} V_L I_L \cos\phi$ — Represents real power transmission in the three-phase AC grid controlled by dispatch centers; $f_{err} = f_{actual} - f_{nominal}$ — The frequency error monitored by SRLDC to manage generation-load balance

Key Points: SRLDC is under the operational control of POSOCO (Power System Operation Corporation Limited), now Grid-India.; It monitors the Southern Regional Grid covering states like Karnataka, Tamil Nadu, Kerala, Andhra Pradesh, Telangana, and Puducherry.; Functions include real-time grid control, electricity scheduling, and settlement of deviation charges.

Advantages: Ensures grid security and stability; Optimization of power transmission costs; Real-time monitoring of interstate load flows

Disadvantages: High complexity in managing multi-state interconnections; Dependency on reliable communication and SCADA infrastructure

Applications: Load frequency control (LFC) in power systems; Automatic generation control (AGC) coordination; Interstate electricity trading management

Additional Info: The five regional centers in India are NRLDC (New Delhi), WRLDC (Mumbai), ERLDC (Kolkata), SRLDC (Bengaluru), and NERLDC (Shillong).. Option B (Chennai) is incorrect as it is a major power hub but does not house the SRLDC head office.

Answer: A is correct — The Southern Regional Load Dispatch Centre (SRLDC) is located in Bengaluru.

Exam Tip: Always remember the regional centers: Northern (New Delhi), Southern (Bengaluru), Western (Mumbai), Eastern (Kolkata), and North-Eastern (Shillong) for grid-related exam questions.
